I need to know the resistivity of german silver wire. I've looked at a few Google sources and I've seen several different results.

Anyone know which value I should use?

Use 18 % nickelsilver, here
http://www.ndt-ed.org/GeneralResources/MaterialProperties/ET/Conductivity_Misc.pdf

18 percent is pretty standard. There is no silver in German Silver: Copper, Nickel, Zinc. The 18percent refers to the percent nickel. Polished, it looks like silver.

I see 18% Nickel Alloy A (under pure silver) is listed as 2.874 x 10^-7

Is this what I should use?

• physics -

330 ohms m
